Ingredients

Why this recipe works

The slow cooker does all the work: it gently cooks the chicken until it's fall-apart tender, while the peppers and onions soften and release their natural sweetness.

The low, steady heat blends the flavors together without any stirring or fussing, resulting in a cohesive, deeply flavorful dish. This hands-off method is ideal for busy weeknights.

The combination of queso blanco and pepper jack cheese creates a rich, creamy sauce with a gentle kick. The queso blanco melts smoothly, while the pepper jack adds a spicy, savory note that complements the chicken and peppers.

This cheese duo is what makes the dish so irresistible, and it also helps keep the chicken moist and juicy.

Notes and substitutions

Use boneless, skinless chicken breasts for the best texture; they cook quickly and shred easily. You can also use chicken thighs for a richer flavor, but adjust the cooking time accordingly. Fresh lime juice adds brightness, but bottled works in a pinch. The peppers and onions add color and texture, so don't skip them.

A 6-quart slow cooker is ideal for this recipe, but a 4-quart will work if you arrange the ingredients carefully. The queso blanco dip should be warmed before adding to help it pour evenly. If you prefer a milder dish, use Monterey Jack instead of pepper jack. For extra heat, add a diced jalapeño or a pinch of cayenne.

• chicken breasts: chicken thighs (boneless, skinless) can be used; cook time may be slightly longer.
• queso blanco dip: Use a store-bought white queso dip or a homemade white cheese sauce.
• pepper jack cheese: Monterey Jack or a Mexican cheese blend works well.
• fresh lime juice: Bottled lime juice can be substituted, but fresh is better.
